IMPROVEMENT IN LOC'OMOTIVE HEAD-LIGHTS.

Speciiication forming part of Letters Patent No. 46.380. dated February14, 1865.

To all whom it may concern:

Be it known that I, THOMAS J. NEWLAND, of Utica, Oneida county, NewYork,have invented a new and usetul Improvement in LocomotiveHead-Lights or RailroadLamps; and I do hereby declare that thefollowingis a full, clear, and exact description of the same, referencebeing had to the annexed drawing, making a part of this specification,which drawing represents a sectional view of the burner containing saidimprovement.

The nature of my invention consists, first, in the use and arrangementof four tubes in the construction of the burner, by means of which thelamp is prevented from leaking and the wick is readily raised andlowered Without its being caused to rotate, as in other cases where ascrew is used and, second, in making the inner tube bell shape at thetop and bottom for the regulation ot' the air to the ilame.

A A is the outer barrel of the wick-tube; B B, the inner one. G C is thescrew, and D D the inner tube with the bell-shaped ends E E and F F. G Gis the wick-thimble, and I a pin therein playing in the screw C U, and Nis a notch in the flange of G, which plays on the way H, attached to theinner side of A.

O O is a milled ring attached to D for turning the screw C G. K is thefeedtube; I I, a circle of Ventilating perforations. M is the button,and L a perforated cup to regulate the ingress of air to the center ofthe wick. The outer and inner barrels of the wick-tube, A A and B B, areof the ordinary form and are united together near the bottom bysoldering them to an interposed ring, as seen at B B. Below this is thecircle of holes J J, through A A, to keep cool the bottom ot the burner.The inside cylinder or barrel, D D, is

beveled outward at both ends,as seen at E E and FF, and just at thebottom ofA A is attached O 0. C C is tted close to B B, and has a screwon its outer surface, and is rivet( d firmly to D D at the top, as seenatE E. The wick-thimble G is of the usual form, and has a pin, I, on itsinner side, which plays into the screw G, while the flange on G hasanotch, N, which slides over the way H, attached longitudinally to theinside ot' A.

To raise or lower the wick, O 0 is turned, which causes G C to turn inthe same direction, and as G cannot turn, by reason ofthe notch A andway H, it is forced to move up or down as O O may be turned by the screwC acting on the pin l.

The ben-shaped @Das 0f D D permit the air A to ascend more freely and tostrike the iiame `nearer to the point of combustion than if the upperend was straight.

The advantages of this form of construction, in addition to that juststated, are, its simplicity and economy; the impossibility of oilescaping, except that which drips over the top of the burner, and thedoing away with the necessity of rotating the wick, as is usual in othercases where the screw is used.

I claim- 1. The combination and arrangement ot' the barrels or cylindersA, B, C, and D, used and operating substantially in the manner and forthe purpose mentioned.

2. The beveled ends of the inner cylinder, D, separately and incombination, used and operating substantially :in the manner and for thepurposes mentioned.
